code for stm32l152 gpio blink led

说明：  使用Jk触发器实现PLL鉴频器电路 还没仿真测试 只作为参考(jk flipflop for PLL frequency discriminator)

红外编码显示在p1口的led灯上，方便大家利用遥控器。(Infrared codes display on the p1 mouth of led lights, facilitate everybody using the remote control. )

按键控制8×8LED点阵屏显示图形,proteus仿真(Button control 8 × 8LED dot matrix screen display graphics)

将遥控接收头接收到的按键编码通过数码管显示出来 能解码的遥控编码必须是NEC 的6221/6121/6222编码方式(The remote receiver receives the key code via the digital display of the remote control code must be able to decode the NEC' s 6221/6121/6222 encoding)

路由器自动开关机省电 由廉价的AT89S52单片机作为控制采集芯片，控制三组定时开关机时间，并且能断电保存用户信息长达五年之久，路由器的控制由单刀双掷开关实现，而且无需另加电源，只须由路由器电源提供。本装置配有人性化操作界面，采用DS1602背光液晶，实现三组开关机时间显示和实时时钟显示。(Router Switcher power saving)
